B. D. STEVENS, OF LAWRENCE, MASSACHUSETTS, ASSIGNOR TO HIMSELF,

SAMUEL (l. CROMBIE, AND G. S. APLETON.

EMPRCVEMENTIN SELF-OILING JOURNAL BOXES AND BEARINGS.

Specification forming part of Letters Patent No. 39,018, dated June 23,1863.

To all whom it may concern Be it known that I, B. D. STEVENS, formerlyof Burlington, in the county of Chittenden, in the State of Vermont, butnow of Lawrence, in the county of Essex and State of Massachusetts, haveinvented certain new and useful Improvements in Self-OilingJournal-Boxes; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, forming a part of this specification, and inwhichf Figure l represents a side view of a journal-box with myimprovements applied there to. Fig. 2 represents a plan or top view ofthe same. Fig. 3 represents alongitudinal section on C D, Fig. 2. Fig. 4represents a view ofthe cap B turned over. Fig. 5 represents a top orplan view ofthe parts C and D with the cap B removed; and Fig. 6represents a cross-section on line A B, Fig. 2.

In Figs. 1, 2, and 3 the shalt A is shown in place, but not in theremaining figures.

llIy journalbox is composed of three partsviz., B, C, and D. The shaftor journal A rests and turns upon D as a bearing, while the latter hasflanges D', which fit-into corresponding depressions in the part G andkeep it in position. The ends of B and (l are turned out a little largerthan the shaft. as indicated in the drawings, while the cap B is groovedout still more a short distance from each end, as seen at B B.

The operation is as follows: The oil being turned into the concave F ofthe cap B descends through the hole e down upon the ring c on the shaftA, thence down through the opening f in the bearing part D into thechamber E of the part 0, from whence it is gradually raised by the ringa., which revolves with` the shaft A, and thrown against the concave bin the cap B, from which it drops upon the shaft and is forced intotheinclined grooves b' b in the cap B, and thereby caused to flow orwork out laterally at the ends of the bearing D, and then drops or runsdown in the spaces C G into the chamber E, to be operated upon by thering a.

This journal-box is simple in construction, but effective in operation.

Having described my improved self-oiling journal box or bearing, .what Iclaim as` my invention, and desire to secure by Letters Patv 1. Thecombination of the ring c with the opening f and chamber E,substantially as and for the purposes stated.

2. The combination, with the parts B, C, and D, of a ring, a, or itsequivalent, upon the journal, substantially as and for the purposesstated.

B. D. STEVENS.
